OS X is dead

After 15 years of large cats and a few California landmarks, Apple's OS X is getting a new name that's actually an old name. Apple's senior VP of software engineering, Craig Federighi announced that, henceforth, the operating system on desktop and laptops will be called macOS.

The first version of the operating system will be called Sierra and will be available today to developers with a public beta available in July. The gold master will launch in the fall.

So the way is open (in effect) for OS 11... can't have Microsoft using a higher OS version number than Apple
